sunmnnenn PUMP.

Application led June 15,

To aZZ whom it may concern Be it known that we, WILLIAM HERMAN ALBRICHT and PATRICK VILLIAM RnAnDoN, citizens of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented new and useful Improvements in Submerged Pumps, of which the following is a specification.

This invention relates to submerged force pumps, the primary object of the invention being to provide a simple, durable and inexpensive construction of pump of the double-acting type which may be operated by hand or any other suitable power'for pumping a large volume and continuous stream of water to a considerable height or for a considerable distance, with a minimum expenditure of power.

A further object of the invention is to provide a pump which dispenses with the use of packing or other parts liable to rapid deterioration or to easily get out of order, and which will always operate free and clear in the presence of dirt, sand, or other refuse and without liability of being clogged thereby.

A still further object of the invention is to provide a pump in which but a comparatively few working parts of a simple type are employed, enabling the pump to be kept in thorough working order and reducing time, labor and cost in making repairs.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:-

Figure 1 is a top plan view of the pump.

Fig. 2 is a vertical longitudinal section thereof.

Fig. 3 is a sectional plan view of the pump cylinder and main gate valve therein.

Fig. 4 is a vertical transverse section on line 4-4 of Fig. 1.

F ig. 5 is a vertical transverse section on line 5 5 of Fig. 1.

Fig. 6 is a perspective-view of the main gate valve within the cylinder.

In the practical embodiment of our invention, we provide a pump casing or cylinder 1 which may be of any suitable form and construction, but which is shown herein as of oblong rectangular form and composed of a base 2 having side walls 3 integral therewith, a removable cover plate 4 being Specification of Letters Patent.

Patented Mar. 8, 1921. 1920. serial No. 389,065.

provided to close the top of the casing, and the ends of said casing being open to provide water inlets 5. The cover or top wall is provided with apertured ears 6 through which pass tie bolts 7 also passing through apertures in cross pieces 8 arranged upon the under side of the bottom wall 2, where by the cover plate is firmly and securely fastened in position. By removing the bolts the cover plate may be lifted od and the interior of the casing or cylinder completely exposed to permit access to the working parts for cleaning, repairs and other purposes whenever required.

At a point centrally of its length the' casing or cylinder l is provided with a discharge outlet 9, suitably threaded for connection with a discharge pipe (not shown) leading to any suitable point for the delivery of the water discharged from the pump. The outflow of water through this port 9 is controlled by a main gate valve 10 arranged within the cylinder. This gate valve 10 extends transversely across the cylinder and is provided in line with one of its vertical edges with pivoted projections 11 engaging bearing recesses 12 in the bottom wall 2 and cover plate 4 whereby said gate valve 10 is adapted to swing in opposite directions longitudinally of the cylinder. The free edge of the gate valve l2 is arranged to move across the port 9 and is limited in its reverse movements by stops 13, said stops being properly positioned to arrest the swinging motion of said gate valve in either direction beyond one side or the other of the port 9 to fully uncover the same for the discharge of water from one end or the other of thecylinder.

The casing or cylinder is divided bythe gate valve 10 into opposite end chambers or compartments 14 and 15 communicating at their outer ends with the respective inlets 5, and mounted to reciprocate in these respective chambers or compartments 14 and 15 are pistons 16 and 17 of like construction, each piston being provided with a pair of outwardly extending like rods 18. The like rods 18 of the respective pistons 16 and 17 are connected by a yoke bar 19 and said yoke bars are connected at their outer ends by tie plates 20 and 21. The yoke bars 19 are ,arranged in superposed relation to the cylinder, and are adapted to reciprocate back and forth above the top wall or cover plate 4. Formed upon the cover plate are transversely extending guide ribs 22 provided with guide grooves 23 receiving the bars 19, whereby said bars are accurately guided in their movements.

Each piston 16 and 17 is provided with a water flow passage or port 24 controlled by a swinging gate valve 25. Each valve 25 is located upon the inner side of its piston and is pivotally mounted at its upper edge. as indicated at 26, along the upper wall ot the port or passage 24, and said valve is movable to closed position within a rabbet or recess 27 formed in the inner side of the valve, whereby a seat tace is provided against which the valve is adapted to close flush with the inner surface of the piston, as will be readily understood. The pistons Iare adapted to be simultaneously recipro- -eated in the same direction by any suitable hand or power mechanism. The mechanism shown in the present instance for this purpose comprises a drive shaft 28 journaled at its lower end in a bearing sleeve 29 formed upon the cover plate 4 and provided with a drive crank 30 coupled by a connecting rod 31 to a pivot or wrist pin 32 on the tie plate 20, whereby on each revolution of the shaft 28 each piston will be given a complete back and forth reciprocatory movement.

In the operation oi the pump, it will be understood that the cylinder and coperating parts are submerged in the body of water, with the shaft 8 extending above the surface of the water to a convenient point for operation by hand or connection with any preferred power mechanism. ln practice, the shaft 28 may be provided with a, hand crank or lever mechanism for operation by hand, or it may be driven by suitable gearing from or connections with a gasolene, electric, steam or other motor. 1n the operation ot the pump, assuming lthe parts to be in the neutral position shown in Fig. 2, it will be understood that when the pistons 16 and 17 are moving in the direction of the arrow, the piston 16 will be on its out or intake stroke and the piston 17 on its in or force stroke. On such outward movement of the piston 16 the valve 25 thereoi vwill be forced open by the pressure of the water which will flow through the port 2li into the chamber 14 between said piston and the main gate valve 10, while on the inward movement of the piston 17 the charge ot water which has previously passed through the port thereof and into the chamber 15 between said piston and the main gate valve 12 will force said gate valve toward the piston 16, or to the position shown in fuli lines in Fig. 3, for the outflow of the water controlled by said piston 17 through the discharge port 9. When the pistons operate on the reverse movement, the converse of the above described action will occur, that is to say, the piston 16 Vwill move inwardly on its force stroke, while the piston 17 will move outwardly on its intake stroke, and on the inward movement ot the piston 16, during which the valve member 25 thereof is closed, the main gate valve 10 will be forced over to the dotted line position shown in Fig. 3 so as to uncover the port 9 to the chamber 14 for the discharge oi' the water from the latter. Hence in the continued action of the pump a constant stream of water will be forced out through the opening 9 for flow to any desired point for use.

In the use of the pump, it may be submerged in the water in a cistern or other reservoir for pumping the water to any delivery point, or may be employed for pumping out flooded portions of a mine, or for pumping out the holds oi leaky ships or for any other desired purpose Vin which a submerged pump can be employed. Inasmuch as the casing or cylinder is fully open at each end to provide inlets of large area, and the pistons are provided with large water passages, a double acting' pump of this construction is adapted for handling a very large volume of water and forcing a stream of water to a considerable height and for a considerable' distance. The construction described also insures a reduction of friction and resistance due to the use of constricted ports or passages, with the result that the pump may be operated at the expenditure of a minimum amount of power. The use of large ports and passages and valves of the construction defined also enables the pump to be employed in turbid water or water containing a large amount ot debris, inasmuch as the large size of the passages will permit foreign matter of various kinds to freely tiow through the pump, thus preventing the pump from being clogged by the accumulation of foreign substances. The

simplicity of the' pump further insures a low cost of maintenance and ease and convenience in making repairs when occasion requ1res.

Having thus fully described our invention, we claim:

1. A submerged force pump comprising a casing having a water inlet at each end and a discharge outlet'at the center thereof, a pivoted main gate valve in said casing movable in opposite directions under water pressure to alternately open and close communication between the outlet and the respective inlets, reciproeatory pistons arranged in the casing on opposite sides of the outlet and each having a water passage and a hinged valve controlling the same and adapted to open on each inward movement of the piston and close' on the outward movement thereof, a pair of rods connected with each piston, yoke bars connecting like piston rods and movable longitudinally above and in guided connection with the casing, connecting elements between the ends of the yoke bars, and means coupled to one of said connecting elements for reciprocating said yoke bars and pistons.

2. A submerged force pump comprising a casing having a water inlet at each end and a discharge outlet at the center thereof, a pivoted main gate in said casing movable in opposite directions under water pressure to alternately open and close communication between the outlet and the respective inlets, reciprocatory pistons arranged in the casing on opposite sides of the outlet and each having a Water passage and a hinged valve controlling the same adapted to open on each inward movement of the piston and close on the outward movement thereof, a pair of 20 rods connected with each piston, yoke bars connecting like piston rods and movable longitudinally above and in guided connection with the casing, connecting elements between the ends of the yoke bars, a crank shaft in rotatable bearing contact with the casing, and a connecting rod between the shaft crank and one of said connecting elements.

In testimony whereof We alix our signatures.
